2 boxes of Wheat Thins for .02!

I ran into CVS yesterday to pick up a couple boxes of wheat thins.  The small boxes are on sale for $1.00 this week, and I had that $1.00/2 printable...so, I was planning on getting them for .50 each!  But, I scanned my CVS card in that coupon machine and out came a $1.00 ECB!!  So, I used it and only paid .02 for both boxes of wheat thins!!
